Wireless headset device capable of providing balanced stereo and method thereof

Abstract

A wireless headset device capable of providing balanced stereo. The wireless headset connects with a stereo output device for giving balanced sounds on both left and right channels. The wireless headset has an encoder/decoder module which decompresses a digital audio package received from a wireless transceiver device into a stereo signal, and delivers it to a connection detecting module. The connection detecting module determines whether the wireless headset connects with the stereo output device. If the answer is negative, the stereo signal will be outputted by a single channel speaker of the wireless headset; otherwise, the signal will come out from the stereo output device which has a two-channel speaker.

         5 . The wireless headset device as claimed in  claim 1 , wherein the communication module comprises:
 a signal converter unit, connected between the encoder/decoder module and the connection detection module, for converting the stereo signal decoded by the encoder/decoder module from a digital signal to an analog signal.   
     
     
         6 . The wireless headset device as claimed in  claim 1 , which further comprises:
 an audio receiver unit, for receiving an external audio input, whereby the external audio input will be send to the signal converter unit to be converted into a digital signal.   
     
     
         7 . The wireless headset device as claimed in  claim 6 , wherein the encoder/decoder module receives the digital signal and encodes it as the digital audio package, then through the second transceiver module the digital audio package is transmitted to the audio transceiver device by the encoder/decoder module. 
     
     
         8 . The wireless headset device as claimed in  claim 1 , wherein the communication module is a Bluetooth module. 
     
     
         9 . The wireless headset device as claimed in  claim 2 , wherein the audio output unit is a USB female connector, and the audio input unit is a USB male connector. 
     
     
         10 . The wireless headset device as claimed in  claim 2 , wherein the audio output unit is a TRS female connector, and the audio input unit is a TRS male connector. 
     
     
         11 . The wireless headset device as claimed in  claim 2 , which further comprises:
 an adapter, which serves for connecting the audio output unit and the audio input unit wherein one side of the adapter connects with the audio output unit and the other side connects to the audio input unit.   
     
     
         12 . The wireless headset device as claimed in  claim 11 , wherein
 the side of the adapter connecting to the audio output unit has a USB male connector, and the side of the adapter connecting to the audio input unit has a TRS female connector, the audio output unit has a USB female connector, and the audio input unit has a TRS male connector.   
     
     
         13 . The wireless headset device as claimed in  claim 1 , wherein the audio transceiver device is a mobile phone or a music broadcasting device.
